| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an undersized wrench or socket, leading to head damage and improper torque application. | Always use a correctly sized wrench or socket that fits snugly onto the hex head to ensure full engagement and prevent stripping. |
| Applying excessive torque, which can lead to thread stripping or bolt fracture. | Consult torque charts for M6 carbon steel fasteners and use a torque wrench for precise and consistent tightening. |
